To all whom it may concern.' shaft D with the projectile body. The Be itknown that I, KARL Winsen, a sub- Vshaft is composed of threecylindrical parts ject of the Emperor of Germany, and a resiof differentdiameter. That part (d1) ofthe dent of Bredeney-on-the-Ruhr, Germany,shaft which is of smallest diameter is loosely have invented certain newand useful lminserted in the sleeve E and in a cap Hoo proveniente inlf'rojectiles, of which the folwhich islsecured to the flange c2 of thesleeve lowing 1s a specification. E. The cap lies with a sphericallsurface The present invention relates to the type against the flange e2and serves for transof projectiles (exploding, illuminating, invInittingto the projectile-body A the preshl() `cendiary and-the likeprojectiles) which is sure which acts on the shaft D when the .65

provided Witha shaft serving for guiding the gun is red. To that end theshaft abuts projectile in the projecting device (the-gun with a shoulderd3 against the cap'H. The barrel for instance). This shaft is forinshoulder is produced by the change in distance necessarywhen theprojectile body ameter between the shaft-part d1 and the proper, whichfor instance contains the longer shaft-part which is of intermedie 70bursting charge, is of greater caliber than diameter. The lattershaft-partis rovid d the gun barrel serving for throwing the prowithribs d* whichv together with t e sha 4tjectile. in the known projectilesof this part (Z2, the diameter of which correspond type the shaft isrigidly` connected with the to the caliber of the smooth barrel, se esprojectile and the shaft and proj ectile'therefor-guiding the shaft inthe gun barrel. 75 fore remain connected together throughout On theshaft D is loosely and slidabl the entire path of fiight.

A projectile having e projectile-`oody, o sheit for guiding theprojectile in the pro.n jecting device, said shaft having driving andnon-restraining connection With the projecting device, and removablyconnected with the projectile-body, and Ineens causing the shaft toseperate from the projectileloody upon the beginning of flight thereof.

3. A projectile having a projectile-body, e shaft for guiding theprojectile in the projecting device and removably connected with theprojectileebody, and ineens causing the shaft to separate from the projectilsbody after firing, seid Ineens comprising e' weight mounted toslide loosely on the shaft,
